While we have no counter facts about re-forestation and I might doubt those facts anyway You probably know this, but for those that don't- a rainforest ecosystem, by it's nature, holds a very high percentage of the available nutrients in the canopy, not in the soil. When the canopy is removed (deforestation), the flow of nutrients to the relatively poor soil stops, and evaporation of water from the now exposed soil increases dramatically. A google search for "desertification" will explain why you don't often hear about reforestation in a rainforest ecosystem. The flow of nutrients is from the soil up. The only way it returns to the soil is when the vegetation falls over, dies, and rots in place. Nutrients aren't airborne (at least not in any usable quantity). You don't hear about reforestation of the rain forest because it costs a lot to buy and use heavy equipment so people generally have a plan before they go to the trouble to cut down trees. Whether that's for development or firewood, putting it back the way it was is either impossible (development) or not timely (fuel use). Demanding someone from the third world to please replant the 90 acres he just cut down before cutting down more when all he can see is inhospital jungle just comes off as crazy yankee talk, right or wrong it's their land to utilize or screw-up.
